[ltp] Re: Linux on the T20

My T20's LT modem never connects over 24k in Qwest territory, before or
after the addition of the sticky shield under the card.  My ordinary 3.7
year old PCI modem (flash reprogrammed to v90) consistently goes 10% faster.
It could go 54k sustained on PacBell lines (yes, the LT is faster down south
too, but still not that fast). It works under linux without special
software, although it's a hassle.  Why spend so much money on lawyering (I
assume that's what's meant by "intellectual property") if you can't keep up
with the old models?  If you assume that anyone who can afford a T20 can go
where there's broadband service, why spend anything on developing a modem?
